White people really are superior

Think about it....20,000 years ago all humans were on a level playing field. They all lived in equal shit and squalor. And through the course of time, white people somehow manage to come out on top.....

how can this be refuted?

Actually, 200 years ago whites had the most filthy living conditions of any race. Victorean England was appalling, even to primitives like native americans. Besides, you say that we came out on top like it's all said and done. There have been other civilizations in history that remained powerful for many times longer than western civilization has flourished. If western civilization loses dominance when oil runs out (next 100 years) then we'll have been one of the shortest lived major civilizations in history.
